Abstract

Patente de Invenção: <B>"PROCESSO PARA PREPARAçãO DE 2-OXO-1,3-DIOXOLANAS MONOHALOGENADAS"<D>. A presente invenção refere-se a um processo para preparação de 2-oxo-1,3-dioxolanas monohalogenadas, da fórmula geral C~ 3~H~ 3~XO~ 3~ (I) em que X é CI ou Br, caracterizado pelo fato de que a monohalogenação é realizada partindo de carbonato de etileno com dihalogenetos de sulfurila, sob irradiação UV e na ausência de solventes.Invention Patent: <B> "PROCESS FOR PREPARING MONOHALOGENATED 2-OXO-1,3-DIOXOLANS" <D>. The present invention relates to a process for the preparation of monohalogenated 2-oxo-1,3-dioxolans, of the general formula C ~ 3 ~ H ~ 3 ~ XO ~ 3 ~ (I) in which X is CI or Br, characterized due to the fact that the monohalogenation is carried out starting from ethylene carbonate with sulfuryl dihalides, under UV irradiation and in the absence of solvents.
